Application filed July 17, 1912. Serial No. 709,880. v

To all whom it may concern:

Be it known that I, GUIDO voN HoRvA'rn, residing at Chicago; in the county of Cook, State of Illinois, and a subject of the King ofHungary, have invented certain new and useful 1 Improvements in Embroidery-Ma chines, of which the following is a specification.

It is the object of the present invention to provide a portable machine for making embroidery stitches on cloth and similar material, the machine being under the ready control of theoperator so that artistic designs and complex patterns may be executed as desired.

The machine hereinafter disclosed as an embodiment of the present invention comprises a needle movable through the cloth and working in conjunction with a looper located above the clothand in position to engage the thread as the needle recedes, lifting the thread sufliciently to form a loop and otherwise controlling the motion of the thread so that successive introductions of the needle through the cloth will produce a succession of loops or chain stitches lying on the face of the cloth and tracing out the design or pattern to be executed.

The special and novel phase of the embodiment here disclosed will be better understood from reference to the following detailed description which is to be taken in conjunction with the accompanying drawings, wherein Figure 1 is a perspective view somewhat diagrammatic, illustrating the machine as arranged for use. Fig. 2 is a side elevation with some parts in section, showing the machine in its initial or inactive position. Fig. 3 shows the machinewith the looper swung back and the needle raised to bring its thread in position to be caught and held by the moving looper. Fig. 4 is a perspective view of the lever mechanism whereby.

the necessary motions are transmitted to the looper and to the needle. Fig. 5 is a side elevation of the thread take up device. Fig. 6 is a transverse section adjacent to the looper and illustrating the operative connections for the needle and the looper mechanism. Figs. 7 8 and 9 are details of the looper in various positions, and Fig. 10 is an enlarged detail view on the line 10-1O of Fig. 6 showing the spiral spring for returning the looper after it has been swung out of normal position.

As indicated in 1, the complete ma- Patented Feb.1"7, 1914. 5

chine is to be used for executing embroidery patterns, as on a piece of cloth 1, which.

may be stretched over a suitable frame 2 as Ind cated. 'Fig. 1 while somewhat. diagrammatic in character, indicates that the complete embroidery machine vmay include a. supporting pedestal 3 carrying a pivotally mounted rectangular frame. 4 serving as a swmging support for the pivotally mounted frame 5 whereon the needle and looper are supported. A suitable operating cable 6 leads back from the frame 5 over suitable sheaves and by way of suitable bell cranks to a foot lever ,7 or other actuating mechanism within reach of the operator. Successive depressions of the foot lever 7 serve to project the heedle through the cloth and,

also serve to actuate the looper whereby each stitch is completed as will hereinafter explained more in detail. Fig. 2 shows the embroidery machine with the several operative parts in their initial position. The frame there disclosed may be of metali-provided at the rear corners with trunnions 8 and 9 to serve as pivotal mountings and having at its front a head section -10 which can be swung outward about a pivotal support 11 when the machine is to he slipped into operative position to embrace the cloth, as shown in Fig. 1. A spring catch 12 cooperating with a projecting raised lug 13 on the head member serves normally to hold the head in its active position, as shown in Fig. 2. Immediately below the head 10 is a work platform 14 which may be pivotally mounted at 15 to permit withdrawal of some of the other parts when desired. The needle-16 is carried in a block 17- mounted to slide in guidewaysformed in four upright guiding bars 18 on the top of which the platform 14 normally rests. The upward or forward movement of the needle is eflected by: means of a cross-head 19 which passes through the block 17 and is connected with a pair of pitmen 20 actuated by cross-bar 21 (Fig. 5) carried by .an arm 22 (Fig. 2) projecting from a head wheel 23 mounted on a stationary horizontal'shaft 24 housed in a box at the lower forward corner of the machine frame. A projecting arm 25 is secured to the head wheel and is provided with an actuating cable 26 which passes over a sheave 27 for connection to operating levers as hereinafter explained. A rope or cable 26 will swing the head wheel 23 and advance the needle 16 upward through the platform 24 and through the cloth resting thereon. A spiral spring 28 housed between the guidemembers 18 and secured to the needle block 17 serves to retract the needle after each ad vance and thus constitutes an automatic returning mechanism for the needle. The needle may be held in its block 17 by means of a set screw 29 (Fig. 6), or in any other suitable manner.

The looper 30 as shown in Figs. 7 to 9 inelusive, is in the nature of a strip of metal bent or cut to circular form and having its front or forward end notched at 31 and rounded ed at 32 so that the looper may engage the loop of thread formed at the side of the needle as shown in Fig.7 when the needle begins its return movement through the cloth, it being understood that the looper is mounted on a central axis and turns or swings at just the proper time relative to the needle movements. The looper 30 is supported solely on two projecting studs 33 and 34 carried by a disk 35 which is mounted on a shaft 36 (Fig. 6) carrying a pulley wheel 37 within which is a spiral spring 61 arranged like a clock spring, see

Fig. 10, having its outer end 62 secured to the head section 10, and its inner end 63 secured to the pulley 37 and serving to return the looper to its initial position after it has been swung to the position shown in Fig. 7 by a pulley or actuating cable 38 which is wound on the pulley wheel 37. A thread guide 39 is mounted within the looper memher and is unsupported except for its engagement with the inner face of the looper and its similar engagement with a shoulder 40 projecting inward from the boxing 41 (Fig. 6) which forms a part of the looper casing or head. In other words, the thread guide 39 floats within the looper member, but cannot rotate because of its frictional engagement with the part 40. A bracket 42 in the form of a resilient metal loop projects from the front face of the thread guide 39 into proximity to the presser foot 43 with which the looper head is provided. The lower corner of the thread guide 39 is bent laterally and narrows down to a spring member 44 which is in position to assist in spreading out the thread loop and which is spaced apart from the bracket 42 sutliciently to admit the needle when it comes upward through the cloth.

The initial position of the looper is illustrated in Fig. 9, there being a thread loop well. spread out by the spring members 42,

44. The next operation consists in swinging the looper backward into the position shown in Fig. 7 and projecting the needle forward through the cloth and withdrawing it, as shown in Fig. 7', just sufficiently to make the thread bulge out at the side of the needle in the form of a loop directly in the path of the notch 31 of the looper. The looper is then advanced into engagement with the thread at the needle and carries the thread upward in the form-of a long loop encircling the thread guide 39 until the looper reaches approximately the position shown in Fig. 8, whereupon the thread drops out of the notch 31 and slips down between the thread guide and the shoulder 40 forming a large loop encircling the spring members 42 and 44 as shown in Fig. 9. The needle has meantime been drawn down through the cloth and the take up device has taken up the slack in the loop.

The take up device to be used in the machine may vary in its construction, but Fig. 5 illustrates one arrangement, which is suitable. That construction includes a take-up arm 45 pivotally mounted on suitable brackets and actuated by a swinging rod 46 which slides through a tubular guide-way in the arm 45 and is pivotally mounted on a projection 47 movable with the cross-head 19' of the needle block. A tension spring 48 overlaps the side of the take-up arm and is so positioned that for a downward swinging movement of the arm the spring will slide upward along the arm and so increase the grip on the thread to be pulled. The take up device is so timed in its operation with and which is then shortened up through the action of the take up device until it is reduced to the form of a small horizontal loop, as shown in Fig. 9, arranged to encircle the needle opening of the presser foot, with the result that the needle when it next comes up through the cloth passes through the horizontal thread loop of Fig. 9 and on delivering its thread to the looper makes the chain stitch illustrated somewhat diagrammatically in Figs. 7 to 9. After each movement of the needle the embroidery machine as a whole is shifted to a new position, the length of stitch being controlled by the operator and the direction of motion being made to conform with the pattern to be executed on the cloth.

Various agencies may be employed to effect the movement of the needle, the looper and the take up device in their proper rela- 'tive sequence, but the embodiment illusthe rear side of the frame and carrying a grooved segment 50 over which the looper actuating cable 38 is .passed, and at the remote end of which that cable is secured. The other arm of the lever is attached to a strong spiral spring 51 anchored to the side of the frame and operative to hold the main lever in the position shown in Fig. 2, but permitting upward swinging movement of that lever under the action of a main operating cable 52 which passes out for connection to the cable 6 of Fig. 1, 'so that it may be actuated through movement of the treadle 7. The pivotal mounting of the lever 49 is in the form of a stationary shaft 53 whereon is loosely mounted a spur gear 54 rigidly attached to a plate having arms 55 and 56 projecting outward for engagement with a lug 57 carried at the side of the lever segment 50. Meshing with pinion 54 is a second pinion 58 rigidly mounted on a transverse shaft 59 which is secured to a lever 60 connected to the needle cable 26. Initially, the several levers are in the position shown in Fig. 2. A. rope or cable 52 will swing lever 49 until its projecting lug 57 engages arm 56 and initiates movement in the gears 54 and '58. In the meantime the looper cable 38 has been pulled sufficiently to swing the looper against the tension of its clock spring into the position shown in Fig. 3, where it is ready to receive the thread from theneedle. A -further movement of lever 49 will revolve the spur gears, thereby pulling upward on the needle lever 60 and forcing the needle upward through the cloth to the position shown in Fig. 3. Then, on release of the main cable 52, the coiled spring 51 will turn the main lever backward and at the same time the tension spring 28 located under the needle block will retract the needle simultaneously with the rotation of the looper under the action of the clock spring housed in the pulley wheel 37.
